[llvm-objdump] - Import the test/Object/X86/no-start-symbol.test test case and rewrite it to use YAML.

This patch removes test/Object/X86/no-start-symbol.test (rewrites
it to use YAML and moves it to llvm-objdump tests folder).

(This test was initially introduced in rL239039, but now there
is no reason to keep the precompiled binary it seems).
